Ball02k Posted November 8, 2016 Share Posted November 8, 2016 Hi all I've read on multiple forums about upgrading A7 sub and adding an amp to power it. I have the standard Audi speakers (no Bose, no B&O). I know what I need but does anyone know how to install? I know about the OEM sub woofer area is very small, just want to know about how to wire to get power and music feed. thanks Quote Link to comment Share on other sites More sharing options...
